METHOD FOR DISCOVERING MULTIPLE ROUTES IN MULTI-HOP NETWORKS, AND NODES FOR SEARCHING FOR MULTIPLE ROUTES

摘要

PROBLEM TO BE SOLVED: To provide a method for discovering multiple routes from a data source node to multiple data destination nodes in a large scale multi-hop mesh network.

SOLUTION: Nodes discover multiple routes to two destinations in an initial discovery phase that includes only two network-wide flooding of packets. The method can also work with one destination. The method can be extended to include more destinations with a proportional increase in the communication overhead. After the completion of the discovery phase, nodes can communicate or forward their own or received data by using any of the available routes.
